I play a number of board and card games with varying degrees of skill, but using "algorithms" to avoid the most obvious mistakes. Depending on the game, if you can beat me, you are probably not a beginner, and perhaps a pretty good player.

How does one evaluate a hand responding to a “strong” two clubs?In your answer below, you said that I (the responder) would become "captain" after the opener's second bid. This means that after opener rebids, e.g. "two spades," it's my prerogative to decide whether or not spades are trump. Why can't I use a "key card system to make that decision."
